Steam Locomotive - Max IHP appears to be incorrect

[Peter Newell]

Following bug reported to me:

"The steam HUD has a performance section, first line of which is Power. First two items are MaxInd and Ind. MaxInd starts with a high figure, Ind starts at zero as the engine is not working.

To accelerate the onset of the probable bug, run the hall at 75% forward and 5% throttle. With the F4 window open as the actual and projected speeds converge open the throttle to 10% and then later again to 15%. You will see the Ind figure will increase as the speed increases, then the MaxInd will start to fall. When these two figures are equal, both will continue to fall and eventually will go into negative figures. Happens much faster with an MSTS eng file, but still happens with the advanced OR file, albeit much slower."

Minor code changes done to correct problem. - #3267 patch added. More to follow.
